Momobeam TRI7-SF Separate Feed 20/15/10 Meter Tri-Band Yagi Antennas
Momobeam TRI7-SF Separate Feed 20/15/10 Meter Tri-Band Yagi Antennas are the smallest triband antenna in the Momobeam lineup that features independent feed points. These antennas use full size reflector and driver elements on both 20 and 15 meters, ensuring excellent gain and bandwidth. On 10 meters, they incorporate a three element design—reflector, driver, and director—optimized to deliver strong, reliable performance across the band. The TRI7 SF series is perfectly suited for multi transceiver stations, offering exceptional versatility thanks to its separate feed architecture. This design allows the antennas to be used simultaneously by three different transceivers, functioning much like three individual monoband antennas when paired with appropriate band pass filters to protect station equipment. As a result, operators can significantly reduce the number of antennas installed on their towers while maintaining full operating capability. Each TRI7 SF antenna includes a complete accessory set, featuring an assembly tool, spare hardware, and a pair of aluminum replacement tubes. Three high quality 3kW RF choke baluns are also supplied as standard—expensive components that many antenna manufacturers offer only as optional extras. These included baluns help ensure clean, efficient operation across all bands. Assembly is intentionally simple and intuitive. The antennas use a square boom design, with every piece of hardware packaged in individually labeled bags and all aluminum tubes clearly marked. This thoughtful organization makes installation fast, clear, and error free, even for complex station configurations. With their separate feed capability, TRI7 SF antennas make it easy for station owners to transition into multi operator contest categories without requiring additional tower space. Key advantages of this solution include a reduced number of installed antennas, lower wind load, elimination of external diplexers or triplexers, and straightforward integration into stacked or multi antenna arrays if desired. These antennas require three coaxial cables and a medium to light duty rotator. With their combination of versatility, efficiency, and thoughtful engineering, the TRI7 SF Separate Feed Yagi Antennas offer a powerful and space efficient solution for serious Amateur Radio operators.

Momobeam Tetra14-SF 40/20/15/10-Meter Separately Fed Yagi Antennas
Momobeam Tetra14-SF 40/20/15/10-Meter Separately Fed Yagi Antennas represent a new generation of compact, high performance HF solutions for contesters, DXers, and multi operator stations. These antennas are designed to eliminate the long standing challenges created by towers crowded with multiple closely spaced monoband arrays. In many installations, such configurations cause unavoidable interaction between antennas, resulting in distorted radiation patterns and degraded performance. The Tetra14 SF overcomes these issues through an innovative separately fed architecture that delivers true multiband capability without compromise. Tetra14 SF features independent feed points for all four HF bands, allowing stations to operate four transceivers or amplifier setups simultaneously. With appropriate band pass filtering, these antennas behave as though each operator has their own monoband Yagi, while requiring only a fraction of the tower space normally consumed by stacked arrays. This approach not only reduces structural load and visual clutter but also produces cleaner patterns, stronger gain, and more predictable performance during competitive operating environments. To ensure top-tier operation on every band, these antennas use carefully optimized element spacing developed through advanced simulation. The 40 meter section employs a compact two element Reflector/Driver design incorporating end loading, a highly effective method pioneered by W6NL. This configuration retains the performance characteristics of a full size Yagi while significantly reducing element length, making installation more practical for a wide variety of tower systems. On 10, 15, and 20 meters, each antenna uses a refined four element arrangement consisting of a reflector, driven element, and two directors, delivering excellent gain and forward directivity across the higher frequency bands. Durability, ease of assembly, and station friendly construction are central to the Tetra14 SF design philosophy. These antennas utilize a strong square boom structure, with all aluminum elements and hardware components clearly labeled for efficient assembly. Every antenna includes an assembly tool, spare hardware, and a complete set of four high quality 3kW RF choke Baluns, a component other manufacturers often sell as an optional upgrade. Installation is straightforward, requiring four coax feedlines—one for each band—and a medium to heavy duty rotator. Momobeam Tetra14 SF Separately Fed 4 Band Yagi Antennas provide exceptional performance, reduced tower complexity, and true multi operator capability. They combine the advantages of monoband arrays into a single, compact, and intelligently engineered system. For contesting groups, DXpeditions, or high-demand stations seeking high performance on 10, 15, 20, and 40 meters, these antennas offer a modern and efficient solution that delivers outstanding on air results.
